Patent CA-2348270-A1 (CA)
Title: Landing gear shock absorber with variable viscosity fluid
Inventor: CARTER JAY W JR
IPC: B64C25/60
Filed: 2001-05-24
Abstract: An aircraft landing gear includes a sealed cylinder divided by a cylinder head to define an upper chamber and a lower chamber. The lower chamber is further divided by a piston having a piston rod passing in a sealed manner through the lower cylinder end. The cylinder head includes one or more orifices, the opening of each containing an electromagnetic coil configured to control the viscosity of the magneto-rheological oil passing therethrough. The electrical current through the electromagnetic coil is continually controlled by a microcomputer with attached sensors for piston position and pressure between the desired piston and the cylinder head, such that the pressure between the piston and the cylinder head decelerates the aircraft evenly throughout the desired piston stroke. The pressure also is limited to a desired maximum level so that, in a severe crash, the shock absorber will absorb significant energy before it fails structurally.

Title: Translucent material displaying ultra-low transport of gases and vapors, and method for its production
Inventor: WERTHEIMER MICHAEL ROBERT
IPC: H01L51/50
Filed: 2001-07-06
Abstract: Emerging organic displays require transparent, flexible substrates with ultra-low permeation of oxygen and water. We propose depositing barrier-coatings onto two separate plastic substrates and bringing them together coated face - to -coated face in permanent contact, for example by laminating, using an ultra-thin layer of an adhesive with low permeability. This may decrease permeation over that of each component film, by two orders of magnitude or more, and it will practically eliminate damaging effects of permeation through larger defects in the coatings, such as those created by roughness and dust particles.

Title: Removal of oil and chloride from oil contaminated material
Inventor: ROBERTS BRIAN G
IPC: B09C1/02
Filed: 1999-12-13
Abstract: A method for chemically removing hydrocarbons from oil contaminated material is described. The method comprises contacting the material containing the oil with a combination of surfactants in an oil carrier similar to or identical to the oil to be removed. This process avoids the use of water. Therefore the process does not compromise the quality of the oil by having water as a contaminant and thus eliminating the possibility of oil contaminated water getting into the environment. In certain examples, when the process is used to remove oil from land based well bore cuttings, the processed well bore cuttings contain high levels of chlorides, which is an environmental problem. In such examples the method also includes contacting the well bore cuttings with a solution of dioctyl sodium sulfosuccinate in water to reduce the chloride concentration. An apparatus designed for this purpose is also described.

Patent CA-2357393-A1 (CA)
Inventor: SNEKKENES VIDAR
IPC: D21C7/00
Filed: 2001-09-17
Abstract: The invention relates to a process for continuous cooking of wood chips at elevated pressure and temperature in a vertical digester (1) for production of chemically dissolved pulp.        Fibre material and cooking liquor are introduced at the top of the digester and pulp is discharged from the bottom of the digester (1), via a line (8) in which the pulp is maintained at substantially the same pressure level, to a pressurized wash (7). More than 50% of the used cooking liquor (black liquor) which is extracted from the system in total is extracted from the wash filtrate of the pressurized wash. At the same time a small portion of the wash filtrate is also to be recirculated to the bottom of the digester as dilution liquid. The pressurized wash is regulated so that a high temperature is maintained in the wash filtrate.        The extraction is regulated so that a net co-current flow is established at the bottom of the digester.      The invention permits increased production in overloaded digesters where substantial extractions of cooking liquor from the digester are made difficult by the increased pulp speed down through the digester.

Abstract: La présente invention concerne l'utilisation d'agents induisant de forts taux de molécules de surface cellulaire, pour fournir des cibles aux immunotoxines agissant contre les mêmes molécules de surface cellulaire. On donne un exemple spécifique, dans lequel l'acide tout-trans rétinoïque (RA) est utilisé pour induire de forts taux d'expression d'antigène de surface cellulaire CD38, dans plusieurs cellules leucémiques myéloïdes et lymphoïdes. Le CD38 est ensuite utilisé en tant que cible, pour délivrer de la phytotoxine (gélonine) aux cellules leucémiques. Le traitement des cellules leucémiques avec le RA induit de forts taux de CD38 dans ces cellules, qui, sans ce traitement, présentent une faible expression de CD38. Les cellules leucémiques induites par RA deviennent ensuite extrêmement sensibles à une immunotoxine, formée à partir d'un anticorps monoclonal anti-CD38 conjugué à la phytotoxine gélonine.

Title: Vertical log singulator with profiled surface
Inventor: GOATER GEORGE H
IPC: B65G47/14
Filed: 2002-04-24
Abstract: This invention provides log singulators which allow for the vertical singulation of piles of logs fed from typical in-feed log decks, so that these logs may be fed individually to typical out-feed conveyors.  Devices provided by this invention may be high-speed singulators occupying minimal floor space area. Singulators provided by this invention comprise arcuately oscillating lifting devices ("primary lifting devices"), preferably rotating synchronously in opposite directions.  Preferably, these singulators elevate logs against vertically successive barriers. These barriers are shaped so that only one of either a largest log or a smallest log, which it is expected that the singulator should handle, can rest on the primary lifting devices and be carried upward at a time. As a result, the lower section of these barriers is shaped in a manner that does not allow two smallest logs to rest side by side on the primary lifting devices, but allows a single smallest or a single largest (or any single log within the range) to rest on the primary lifting devices and be raised upward. Singulators provided by this invention may also comprise an unloading station, which receives the logs from the primary lifting devices and directs them to the out-feed conveyor.
